conf: reimplement virDomainNetResolveActualType in terms of public API

Browse Source 
Now that we have the ability to easily open connections to secondary
drivers, eg network:///system,  it is possible to reimplement the
virDomainNetResolveActualType method in terms of the public API. This
avoids the need to have the network driver provide a callback for it.
